Question

Simplify the expression where possible. (r^3) -2

Answer 1

r^-6

Explanation:

Answer 2

`\bf ~~~~~~~~~~~~\textit{negative exponents}\\\\ a^(-n) \implies \cfrac{1}{a^n} \qquad \qquad \cfrac{1}{a^n}\implies a^(-n) \qquad \qquad a^n\implies \cfrac{1}{a^(-n)} \\\\ -------------------------------\\\\ (r^3)^(-2)\implies r^(3\cdot -2)\implies r^(-6)\implies \cfrac{1}{r^6}`
